Depending on whether asymmetric carbon atoms are present, the compounds of the invention can be present as mixtures of isomers, especially as racemates, or in the form of pure isomers, especially optical antipodes.

Salts of compounds having salt-forming groups are especially acid addition salts, salts with bases or, where several salt-forming groups are present, can also be mixed salts or internal salts.

Salts are especially the pharmaceutically acceptable or non-toxic salts of compounds of formula (I).

Such salts are formed, e.g., by compounds of formula (I) having an acid group, e.g., a carboxy group or a sulfo group, and are, e.g., salts thereof with suitable bases, such as non-toxic metal salts derived from metals of groups Ia, Ib, IIa and IIb of the Periodic Table of the Elements, e.g., alkali metal salts, especially lithium, sodium or potassium salts; or alkaline earth metal salts, e.g., magnesium or calcium salts; also zinc salts or ammonium salts, as well as salts formed with organic amines, such as unsubstituted or hydroxy-substituted mono-, di- or tri-alkylamines, especially mono-, di- or tri-lower alkylamines; or with quaternary ammonium bases, e.g., with methyl-, ethyl-, diethyl- or triethyl-amine; mono-, his- or tris-(2-hydroxy-lower alkyl)-amines, such as ethanol-, diethanol- or triethanol-amine; tris-(hydroxymethyl)-methylamine or 2-hydroxy-tert-butylamines; N,N-di-lower alkyl-N-(hydroxy-lower alkyl)-amines, such as N,N-dimethyl-N-(2-hydroxyethyl)-amine or N-methyl-D-glucamine; or quaternary ammonium hydroxides, such as tetrabutylammonium hydroxide.

Compounds of formula (I) having acid and basic groups can also form internal salts.

For isolation and purification purposes it is also possible to use pharmaceutically unacceptable salts.

The compounds of the present invention have enzyme-inhibiting properties. In particular, they inhibit the action of the natural enzyme renin. The latter passes from the kidneys into the blood where it effects the cleavage of angiotensinogen, releasing the decapeptide angiotensin I which is then cleaved in the lungs, the kidneys and other organs to form the octapeptide angiotensinogen II. The octapeptide increases blood pressure both directly by arterial vasoconstriction and indirectly by liberating from the adrenal glands the sodium-ion-retaining hormone aldosterone, accompanied by an increase in extracellular fluid volume. That increase can be attributed to the action of angiotensin II. Inhibitors of the enzymatic activity of renin bring about a reduction in the formation of angiotensin I. As a result a smaller amount of angiotensin II is produced. The reduced concentration of that active peptide hormone is the direct cause of the hypotensive effect of renin inhibitors.

Thus, the compounds of the present invention may be employed for the treatment of hypertension, atherosclerosis, unstable coronary syndrome, congestive heart failure, cardiac hypertrophy, cardiac fibrosis, cardiomyopathy postinfarction, unstable coronary syndrome, diastolic dysfunction, chronic kidney disease, hepatic fibrosis, complications resulting from diabetes, such as nephropathy, vasculopathy and neuropathy, diseases of the coronary vessels, restenosis following angioplasty, raised intra-ocular pressure, glaucoma, abnormal vascular growth, hyperaldosteronism, cognitive impairment, alzheimers, dementia, anxiety states and cognitive disorders.

As described above, the compounds of the present invention have enzyme-inhibiting properties. In particular, they inhibit the action of the natural enzyme renin. Renin passes from the kidneys into the blood where it effects the cleavage of angiotensinogen, releasing the decapeptide angiotensin I which is then cleaved in the lungs, the kidneys and other organs to form the octapeptide angiotensin II. The octapeptide increases blood pressure both directly by arterial vasoconstriction and indirectly by liberating from the adrenal glands the sodium-ion-retaining hormone aldosterone, accompanied by an increase in extracellular fluid volume which increase can be attributed to the action of angiotensin II. Inhibitors of the enzymatic activity of renin lead to a reduction in the formation of angiotensin I, and consequently a smaller amount of angiotensin II is produced. The reduced concentration of that active peptide hormone is the direct cause of the hypotensive effect of renin inhibitors.

The action of renin inhibitors may be demonstrated inter alia experimentally by means of in vitro tests, the reduction in the formation of angiotensin I being measured in various systems (human plasma, purified human renin together with synthetic or natural renin substrate).

Inter Alia the Following In Vitro Tests may be Used:

An extract of human renin from the kidney (0.5 mGU [milli-Goldblatt units]/mL) is incubated for one h at 37° C. and pH 7.2 in 1 M aqueous 2-N-(tris-hydroxymethylmethyl)-amino-ethanesulfonic acid buffer solution with 23 μg/mL of synthetic renin substrate, the tetradecapeptide H-Asp-Arg-Val-Tyr-Ile-His-ProPhe-His-Leu-Leu-Val-Tyr-Ser-OH. The amount of angiotensin I formed is determined by radioimmunoassay. Each of the inhibitors according to the invention is added to the incubation mixture at different concentrations. The IC₅₀ is defined as the concentration of a particular inhibitor that reduces the formation of angiotensin I by 50%.

Recombinant human renin (expressed in Chinese Hamster Ovary cells and purified using standard methods) at 4 nM concentration is incubated with test compound at various concentrations for 1 h at RT in 0.1 M Tris-HCl buffer, pH 7.4, containing 0.05 M NaCl, 0.5 mM EDTA and 0.05% CHAPS. Synthetic peptide substrate Arg-Glu(EDANS)-Ile-His-Pro-Phe-His-Leu-Val-Ile_His_Thr-Lys(DABCYL)-Arg9 is added to a final concentration of 2 μM and increase in fluorescence is recorded at an excitation wave-length of 340 nm and at an emission wave-length of 485 nm in a microplate spectro-fluorimeter. IC₅₀ values are calculated from percentage of inhibition of renin activity as a function of test compound concentration (Fluorescence Resonance Energy Transfer, FRET, assay).

Recombinant human renin (expressed in Chinese Hamster Ovary cells and purified using standard methods) at 1 nM concentration is incubated with test compound at various concentrations for 1.5 h at 37° C. in 0.1 M Tris/HCl pH 7.4 containing 0.05 M NaCl, 0.5 mM EDTA and 0.025% (w/v) CHAPS. Synthetic peptide substrate Ac-Ile-His-Pro-Phe-His-Leu-Val-Ile-His-Asn-Lys-[DY-505-X5] is added to a final concentration of 5 μM. The enzyme reaction is stopped by adding 6 μL of 1.0% TFA. The product of the reaction is separated by HPLC and quantified by spectrophotometric measurement at 505 nM wave-length. IC₅₀ values are calculated from percentage of inhibition of renin activity as a function of test compound concentration.

Recombinant human renin (expressed in Chinese Hamster Ovary cells and purified using standard methods) at 3.3 nM concentration, 125I-NVP-AJI891-NX-1 (0.27 μCi/mL) and streptavidin-SPA (0.67 mg/mL) beads are incubated with test compound at various concentrations for 2.0 h at RT in 0.1 M Tris/HCl pH 7.4 containing 0.5M NaCl and 0.5% (w/v) Brij35. At the end of the incubation time, the plates are centrifuged (55 g, 60 seconds) and counted in a Wallac MicroBeta reader. IC₅₀ values are calculated from percentage of displacement of radioligand binding to renin as a function of test compound concentration.

In animals deficient in salt, renin inhibitors bring about a reduction in blood pressure. Human renin may differ from the renin of other species. In order to test inhibitors of human renin, primates, e.g., marmosets (Callithrix jacchus) may be used, because human renin and primate renin are substantially homologous in the enzymatically active region. Inter alia the following in vivo tests may be used:

The test compounds are tested on normotensive marmosets of both sexes having a body weight of approximately 350 g that are conscious, allowed to move freely and in their normal cages. The blood pressure and heart rate are measured via a catheter in the descending aorta and recorded radiometrically. The endogenous release of renin is stimulated by the combination of a 1-week low-salt diet and a single intramuscular injection of furosemide (5-(aminosulfonyl)-4-chloro-2-[(2-furanylmethyl)amino]benzoic acid) (5 mg/kg). 16 h after the injection of furosemide the test compounds are administered either directly into the femoral artery using an injection cannula or, in the form of a suspension or solution, via an oesophageal tube into the stomach, and their action on the blood pressure and heart rate are evaluated. In the in vivo test described, the compounds of the present invention have hypotensive action at doses of from approximately 0.003 to approximately 1 mg/kg i.v. and at doses of from approximately 0.3 to approximately 100 mg/kg p.o.

Alternatively, renin inhibitors may be tested on male normotensive marmosets weighing 250 to 500 g that are conscious, allowed to move freely and in their normal cages. The blood pressure, and heart rate are measured via a catheter placed in the descending aorta and recorded radiometrically. Electrocardiogram are obtained by placing electrodes of transmitter in lead II. The endogenous release of renin is stimulated by two intramuscular injection of furosemide (5-(aminosulfonyl)-4-chloro-2-[(2-furanylmethyl)amino]benzoic acid) (10 mg/kg) 43 and 19 hours prior compound application. Test compounds are administered either directly into the femoral artery using an injection cannula or, in the form of a suspension or solution, via an oesophageal tube into the stomach, and their action on the blood pressure, heart rate and ECG are evaluated. In the in vivo test described, compounds of the present invention have hypotensive action at doses of from approximately 0.003 to approximately 0.3 mg/kg i.v. and at doses of from approximately 0.31 to approximately 30 mg/kg p.o.

The compounds of the present invention also have the property of regulating, especially reducing, intra-ocular pressure.

The extent of the reduction in intra-ocular pressure after administration of a pharmaceutical active ingredient of formula (I) according to the present invention can be determined, for example, in animals, for example rabbits or monkeys. Two typical experimental procedures that illustrate the present invention, but are not limited to in any way, are described hereinafter.

The in vivo test on a rabbit of the “Fauve de Bourgogne” type to determine the intra-ocular-pressure-reducing activity of topically applied compositions can be designed, for example, as follows: The intra-ocular pressure (IOP) is measured using an aplanation tonometer both before the experiment and at regular intervals of time. After a local anaesthetic has been administered, the suitably formulated test compound is applied topically in a precisely defined concentration (e.g. 0.000001-5% by weight) to one eye of the animal in question. The contralateral eye is treated, for example, with physiological saline. The measured values thus obtained are evaluated statistically.

The in vivo tests on monkeys of the species Macaca Fascicularis to determine the intra-ocular-pressure-reducing activity of topically applied compositions can be carried out, e.g., as follows: The suitably formulated test compound is applied in a precisely defined concentration (e.g. 0.000001-5% by weight) to one eye of each monkey. The other eye of the monkey is treated correspondingly, for example with physiological saline. Before the start of the test the animals are anaesthetised with intramuscular injections of, for example, ketamine. At regular intervals of time, the intra-ocular pressure (IOP) is measured. The test is carried out and evaluated in accordance with the rules of “good laboratory practice” (GLP).

The structure of final products, intermediates and starting materials is confirmed by standard analytical methods, e.g., microanalysis, melting point (m.p.) and spectroscopic characteristics, e.g., MS, LC/MS, IR, NMR. In general, abbreviations used are those conventional in the art.

EXAMPLE 1 General Procedure (I)

Preparation of the Starting Acid:

a) (2S,4S,5S,7S)-5-tert-Butoxycarbonylamino-4-(tert-butyl-dimethyl-silanyloxy)-2-isopropyl-7-[4-methoxy-3-(3-methoxy-propoxy)-benzyl]-8-methyl-nonanoic acid

Triethylamine (NEt₃) (7.2 mL, 51.6 mmol, 3.0 equiv.) followed by dimethylamino-pyridine (DMAP) (640 mg, 5.2 mmol, 0.3 equiv.) is added to a solution of (2S,4S,5S,7S)-5-tert-butoxycarbonyl amino-4-hydroxy-2-isopropyl-7-[4-methoxy-3-(3-methoxy-propoxy)-benzyl]-8-methyl-nonanoic acid (9.53 g, 17.2 mmol, 1.0 equiv.) and TBDMSCI (10.3 g, 68.7 mmol, 4.0 equiv.) in dimethylformamide (DMF) (100 mL) at room temperature (RT). The reaction mixture is stirred at RT for 16 hours before water (H₂O) is added. Extraction with ethyl acetate (EtOAc), drying [sodium sulphate (Na₂SO₄)] and evaporation of the solvent affords the crude product. Flash column chromatography [600 g silicon dioxide (SiO₂), hexane:EtOAc 5:1] yields the double TBDMS-protected product as a colorless oil.
